Fix some warnings

- Add dependency on org-mode in case I ever install this as a package.
- Require org for `org-collect-keywords', `org-timestamp-to-time',
  `org-timestamp-from-string', and `org-html-export-as-html'.
- Move definition of `tekuti-host' to before it's used.
- Rename `args' to `_' to signify it's not used for anything.
